---------------------------------------

             Summary: Account for netty direct allocations in direct memory limit
                 Key: FLINK-14631
                 URL: https://issues.apache.org/jira/browse/FLINK-14631
             Project: Flink
          Issue Type: Sub-task
          Components: Runtime / Task
            Reporter: Andrey Zagrebin
             Fix For: 1.10.0


At the moment after FLINK-13982, when we calculate JVM direct memory limit, we only account for memory segment network buffers but not for direct allocations from netty arenas in org.apache.flink.runtime.io.network.netty.NettyBufferPool. We should include netty arenas into shuffle memory calculations.
